Zero Trust Networking Idea
What is Zero Trust networking in practical engineering terms (not marketing)?
Answers use simple, clear English.
Quick interview answer
Do not trust the network location alone. Authenticate and authorize every request, encrypt everywhere, segment aggressively, and continuously evaluate device/user risk. Practically: identity-aware proxies, mTLS, short credentials, device posture checks, and least privilege — not a single product purchase.

Full explanation
VPN-only perimeter models fail when phishing lands inside the VPN.
Real example & use case
Engineers access admin tools via identity-aware proxy with MFA, not by joining a flat corporate VLAN.
Pros & cons
Pros: better fit for cloud/remote work. Cons: requires mature identity and observability investments.
